What are the different types of coal? PDF version. The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock.
This type of coal is what you might burn in your home. There are 7.3 billion tons of anthracite reserves in the United States, mainly in Pennsylvania. Bituminous coal is the most plentiful type of coal in the United States. It is mainly found in the eastern and middle parts of the North American continent.
